Legrand says its U.S. headquarters in West Hartford has earned LEED status from the U.S. Green Building Council.

The French company manufactures components and systems for electrical and digital infrastructures — such as switches, sockets, enclosures, power supplies, etc. — at its 263,000-square-foot West Hartford campus, which has five buildings including one that is nearly 100 years old.

Legrand notched 48 points out of a possible 100 in the LEED rating system, which stands for Leadership in Energy and Environmental Design.

LEED is typically scored in a silver-gold-platinum system, but since Legrand's project was on an existing building and not a new one, those distinctions don't apply.

"Obtaining LEED certification for our West Hartford facility is a major achievement for our entire company," said John Selldorff, president and CEO of Legrand North and Central America.

To earn its status, Legrand used a digital tracking system called Arc, which submits actual building performance data to the Green Building Council on energy, waste, water, human experience and transportation.

Legrand said it wanted to pursue LEED certification using actual performance data to leverage several years of efforts to improve its environmental performance.

In late 2016, Legrand joined more than 200 large companies that pledged ambitious reductions in their greenhouse gas emissions that align with the United Nations' 2015 climate convention, an agreement that President Donald Trump announced the U.S. would pull out of.
